WALK-OVER CAR-SEAT.

SPECIFICATION forming part of Letters Patent No. 645,462, dated March 13, 1900.

Application filedNovember 20, 1899. Serial No. 737,695. (No model.) v

To @ZZ whom it may concern:

Be it known that we, ARTHUR C. DEvEEELL and .IULIUS J. LAKE, of St. Paul, Ramsey county, Minnesota, have invented certain new and useful Improvements in Walk-Over Car- Seats, of which the following is a specification.

The invention relates to seats particularly adapted for railway-coaches wherein it is desirable to construct the seats in such a manner that they may be reversed to face at all times the front of the car'.

One object of the invention is to provide an improved mechanism by means of which the seat-back may be easily and quickly moved from one side of the seat to the other, the seat-back remaining during its movement in an upright position, both sides or faces of the back being alternately presented for wear.

A further object is to simplify the operating mechanism, thus rendering the device less expensive to manufacture, while not in any Way detracting from its strength or durability.

A further object is to provide a walk-over mechanism which shall be neat and orna mental in appearance and readily applicable to all forms of car-seats in use, being independent of the seat-arms.

The invention consists generally in vario us constructions and combinations, all as hereinafter described, and particularly pointed out in the claims.

In the accompanying drawings, forming part of this specification, Figure l is a perspective of a car-seat with our invention attached thereto. Figs. 2 and 3 are details of the operating mechanism.

IIn the drawings, 2 represents the frame of the seat of any suitable material, usually wood, having the upright end arms 3, one of which in the perspective view is broken away to show the operating mechanism. At each end of the frame 2, near the upright arm, are the cross-bars 4, preferably of angle-iron, having longitudinal slots 5 in their horizontal flanges at a point preferably midway between the ends of the bars. The bars may be secured to the frame ofthe seat by any suitable means, and to their upright flanges, above the slots 5, links or bars 6, preferably 0f cast metal, are pivotally secured, the lower ends of said bars being adapted to move back and forth within said slots, which form guides when the seat-back is being moved from one side of the seat to the other. The bars or links 6 normally stand in an inclined position and at their outer ends are pivoted to the frame of the seat-back 8, that -is upholstered upon both sides, as is usual in seats of this kind, both sides being used. To hold the links 6 and the back of the seat in the proper position, we provide links 9 9, pivoted to the upright flanges of the bars 4, preferablynear their ends, and having T-pius 10 l0 at their opposite ends that are adapted to slide in parallel longitudinal guide-slots ll l1 in the bars or links 6. These slots are of suflicientlength to permit the seat-back and the bars 6 to be swung from one side of the seat to the other while the T-pins are traveling from one end of the guides or slots to the other. Should the vseat-back be in the position shown in the drawings, the front links will be in their down position, helping to tie the side bars, while the mainpweight and strain will be borne by the rear links, their buttons or T-heads being in the upper ends of their slots, supporting the bars 6 in the desired inclined position. The position of the links with respect to their guides or slots will of course be reversed when the seat-back is thrown over to its other position.

To prevent the seat-back 8 from turning on its pivots at the upper ends of the barsl 6, we provide the short links l2,piv0ted to the frame of the seat-back and having T-heads corresponding to those heretofore described that are slidable in the short slots 13, provided in the bars 6 at a point preferably near the upper ends of the slots 1l. The T-heads on the links 9 and 12 are preferably cast integral therewith and at an angle to the longitudinal axis of said links, so that when the parts are put together the links will be held at the proper angle to permit the T-heads to slip into the slotsand when the links are secured on their pivots and in their normal operative position the T-heads will be crosswise of the slots and cannot become disengaged therefrom. The links and bars comprising the Walkfover mechanism are all preferably of IOO malleable castings and require no finishing or machine-work except the pivots and can therefore be rapidly turned out and assembled. If desired, the metal parts maybe nickeled or otherwise finished to present a more ornamental appearance to the car-seat.

In operation the seat-back is grasped and moved toward the opposite side of the seat, the bars 6 swinging on their pivots, the short links 9 9 sliding in the slots 1l until the seatback has been moved to the opposite side of the seat, when the links 9 9 will have traversed the slots ll and will lock the bars 6 and hold them and the seat-back securely in position. During the movement of the bars 6 the short links l2, sliding in the slots 13, permit the seatback to swing on its pivots and adjust itself at the proper inclination with respect to the car-seat.

It is obvious that various modifications of our invention will readily suggest themselves to one skilled in the art, and we do not contine the invention to the construction herein shown and described.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- 1. In a walk-over car-seat,the combination, with a swinging bar and a seat-back thereon, of a swinging link having a sind sliding in said bar, and whereon said bar is supported when at the limit of its backward movement, substantially as described.

2. In a Walk-over car-scat, a bar swinging on a fixed pivot, a seat-back carried by said bar, links also swinging on fixed pivots upon opposite sides of said bar andv having pivotal sliding connections therewith and said links, respectively, supporting said bar when at the limit of its forward-and-backward movement, substantially as described.

3. In a walk-over car-seat, bars swinging on fixed pivots, a seat-back carried by said bars, links-also swinging on fixed pivots upon opposite sides of said bars and having pinand-slot connections therewith and supporting said bars and said seat-back when at the limit of their forward-and-backward movement, substantially as described.

4. In a walk-over car-seat, a bar swinging on a fixed pivot, a seat-back carried by said bar, a link also swinging on a fixed pivot and having a sliding pivotal connection With said bar and supporting the same when at the limit of its backward stroke, forming at that point with said bar and with its base or support a triangular bracing-frame that is collapsed when said bar is swung to its forward position, substantially as described.

5. In a walk-over car-seat, bars swinging on fixed pivots near the ends of the seat, a seat -back carried by said bars, links also swinging on fixed pivots upon both sides of said bars and having sliding pivotal connections therewith, respectively, and supporting the same when at the limit of their backwardand-forward stroke, forming at those points with said bars and with their base or support a seat-back pivotally supported by said bars,

means preventing the tilting of said seatback, links -swinging on fixed pivots near the front and rear of said seat and having their free ends slidable in the guides in said bars and whereby the travel of said bars in either direction is controlled, substantially as described.

8. The combination, with a seat, of' bars 6 pivotally supported thereon and having guides, the short links pivotally supported near the front and rear of said seat, and having T heads or pins movable in the guides in said bars 6 and aseat-back pivotally supported on -said bars 6, substantially as described.

9. The combination, with a car-seat, of the bars 6 pivoted thereon and having guides,

the seat-back pivoted on said bars, the links l2 pivoted to said seat-back and slidable in the guides on said bars and the guiding and supporting links 9 9 pivoted on said car-seat and sliding in guides in said bars, substantially as described.

l0. The combination, with the car-seat, of the bars 6 pivoted thereon and having guidev'slots ll, the seat-back 8 pivoted on said bars,

means preventing said seat-hack from turning on its pivot when in its normal position, and the links 9 9 pivoted on said car-seat and having T-heads slidable in said slots 1l, for the purpose specified.

ll. In a walk-over car-seat, the combina tion with a swinging back of swinging bars at opposite ends thereof, joined, and supporting the said back, and side links having sliding connections with one of said swinging bars at one end of said back, and the length of said links being less than the distance betweenl the pivot of the swinging bar and thehighest point of travel thereon of said links, substantially as described. l

In witness whereof we have hereunto set our hands this lth'day of November, 1899.
